why are the head gaskets for the slant have 2 different size bores. Mahle 1162VC shows a 3.25 bore and the Felpro 7918PT1 shows the 3.4 bore. Both for the 225 slant 6. Inquiring minds want to know.
 
no /6 had a 3.2-anything bore. Dont know what youre seeing. Misprint? the 3.4 bore is right, bore holes in most head gaskets is 3.5-something. there have been threads on this very thing within the last 6 months or so right here in this forum. chances are your combustion chamber (in the head) is bigger than 3.4. Mine was. and is.

I understand what you are saying but if you look up the part # specs for Mahle 1162VC it plainly states in the specs that the bore is 3.25. It isnt a misprint unless it came from the mfg. I saw it on the screen at Oreilly's and I saw it on the internet. I know the bore is 3.4 because I gauged it on the cylinder but never the less somebody is going to order a head gasket one day and get one that isnt right. I didnt know by what Chrysler did back in the day if they had 2 different sizes.
 
They doubled down on the wrong bore size with the metric spec too @ 82.55mm. No pic where I looked it up.

All stock Slantys are 3.40". The '41-'60 218/230 flathead six the Slanty replaced had a 3.25" bore, but which does Mahle have wrong; part#, description/specs, application?

who knows. I just hope that when someone orders a new head gasket they make sure what they are ordering.
